Select it from the lamp schedule inside the existing fixture. The listed lamp configuration is 2 X F54T5HO, which should be checked as a complete lamp-and-count combination.

Plan the electrical connection around this model’s 120V AC rating. For the ballast compartment layout, allow for the listed length 16.70 in., width 1.18 in., height 1.00 in. and the installation clearances required by its instructions. Follow the wiring diagram for this model when making the replacement connections.

Buying tip: Match the lamp designation, number of lamps and supply voltage to the existing ballast.
